This work tackles the problem of the L2 – L∞ filtering for continuous-time delay systems with polytopic uncertainties. Based on the parameter dependant Lyapunov function approach (PDLFA), we propose less conservative results by means of a linear matrix inequalities. The use of slack variables provide filter design conditions with less conservativeness. This approach is illustrated by popular numerical...
This paper is concerned with the problem of robust full-order ℋ∞ filter design for uncertain discrete-time linear systems. The uncertainties are supposed to be time-invariant and to belong to a polytopic domain. The main novelty is the fact that the filter contains an arbitrary number of past states and past system output measures, yielding a filtering system with memory. Linear matrix inequality...
This note considers the popular anti-windup design problem for linear systems with saturating actuators. The main contribution of this paper is providing the synthesis LMIs to obtain the gains of the dynamic anti-windup compensator in a structure that delays the activation of the anti-windup. The basic idea is to apply Anti-Windup when the performance of saturated system faces substantial degradation...
Video content summarization provides an effective way to accelerating video browsing and retrieval. In this paper, we propose a novel approach to automatically generate the video summary. Firstly, the video structure is analyzed by spatio-temporal analysis. Then, we detect video non-trivial repeating patterns to remove the visual-content redundancy among video stream. Moreover, an importance evaluation...
